Adana Metro () is a rail rapid transit system extending along a north–south corridor through Adana, with 13 stations. It can transport 21,600 passengers per hour per direction. The total travel time on the metro, end to end, takes 21 minutes, including all stops. History The rapid transit system for Adana was initiated in 1988 after requests from the mayor Aytaç Durak and the Çukurova University rector Mithat Özsan to the Ministry of Transportation. A feasibility report was completed on May 30, 1990, by the consortium of PMBI A.Ş. and Brinckerkoff Int.Inc. The report was approved by the State Planning Agency and the construction of the rapid transit system was included in the 1993 investment program. In 1996, the project was contracted to Adtranz-Alarko-ABB Electric Consortium for $US 340 million. To accommodate the new residential developments along the project route and to better integrate northern and southern Adana, the Adana Metropolitan Municipality decided to make an amendment to the project plan by extending the line to southern Adana. The southernmost point of the initial project had been the D-400 state road. Amendments were approved by State Planning Agency in 1999 and the construction of the metro started on 28 January 1999. Unexpected costs increases during the construction of the Metro led to the need for extra funding for the project. Metropolitan Municipality made a request to State Planning Agency for new funding, but the request was declined. As a result, construction of the Metro stopped in 2002. After 6 years, the Municipality was able to get approval for new funding of $US 194.2 million and construction resumed in 2008. On 18 March 2009, the Metro was partially opened for the long section between Hastane and Vilayet stations, with 36-car fleet purchased from Hyundai Rotem. After 3 months of free service, this section of the Metro was closed to service for completing the underground section between Vilayet and Akıncılar. All sections of the Adana Metro opened for full public service on 14 May 2010. The cut-and-cover tunnels with a diameter of , a depth between and length, were constructed as the part of metro construction. The tunnels constructed a few meters deeper than the underground water level (12 m). Operations Adana Metro is a long double track rail line, of which is underground (in cut and cover tunnels), is in trench, is elevated, and is at-grade. Service The Metro runs from
